EUGENE LUCAS, OF NEW YORK, N. Y.

BOLT.

fiPECIPICATION forming part of Letters Patent No. 327,887, dated October6, 1885. Application filed January 29, 1885. Serial No. 154,373. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, EUGENE Looks, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Bolt-Sockets, of which the following is aspecification.

My invention consists in the combination, with a bolt-socket, ofextensions or legs formed on said socket, a spring-supported follower,which fits the socket and can move longitudinally therein, and stopswhich are secured to the follower and adapted to engage the lower edgesof the socket; and also in the combination, with a bolt-socket, ofextensions or legs formed on said socket, a springsupported follower,which fits the socket and can move longitudinally therein, stops whichare secured to the follower and adapted to engage the lower edges of thesocket, and a disk secured to the extension or legs formed on the socketand provided with a hole or holes.

In the accompanying drawings, Figure 1 represents a longitudinalvertical section in the plane g 3 Fig. 3, with the follower in itsnormal or upper position. Fig. 2 is a vertical section in the sameplane, with the follower depressed. Fig. 3 is a transverse horizontalsection in the plane at 00, Fig. 1. Fig. 4 is a top view. Fig. 5 is aside view of the socket placed in position to receive a bolt.

In the drawings, the letter A designates the socket, which may be of asquare, rectangular, circular, or any other suitable cross-section, andwhich is provided with extensions or legs a, to the lower part of whichare secured webs b,- or said webs may be cast integral with theextensions.

To the webs b is secured by means of screws b, or by other suitablemeans, a disk, B, which is provided with a hole or holes, a, in orderthat any water which may enter the socket will readily pass away or soakinto the floorbeams.

O is a followcr,which snugly fits the socket, and is adapted to move upand down therein, said follower being supported on a spring, D, thelower end of which rests on the disk B, or else, if the disk is omitted,it rests directly on the floor-beam. To the follower G are secured,either by screws or solder, legs which form stops 6, and in thedrawings, which show a square socket, four of said stops are used, andthe lower ends of the stops are bent, so as to project outward into thespace between the extensions, but not beyond the outer surface of thesame. The stops e are of such a length that when the follower C is flushwith the upper edges of the socket the projecting portions f engage thebottom edges of the socket and the follower O is stopped. Instead ofbending the stops lugs may be formed on the same, or pins or theirequivalent may be secured thereto. The stops also serve to steady thefollower C and prevent the same from turning or bending.

The top of the socket is provided with flanges g, which are sunk in thefloor and secured by screws at g g in the usual manner, whereby thesocket is retained in place. In Fig. 5 the socket is shown in position,and in this figure E is the bolt, which is secured to the door in theusual manner, and is in its locking position.

The object of my bolt-socket is to preventthe filling of the hole forthe reception of the bolt with dust, &c. All dust or other matter whichsettles on the follower, when the same is in its depressed position, ispromptly ejected when the bolt is withdrawn, and as the follower fitssnugly in the socket no dirt can pass between the same and the socketand into the socket.

I am aware that bolt-sockets of a similar description and purpose havebeen made prior to my invention, but none of these absolutely preventedthe dust from settling in the socket and in time filling the same.

I do not broadly claim devices which pre vent the entrance of dust intothe bolt-socket; but

What I claim, and desire to secure by Letters Patent, is

1. The combination, substantially as hereinbefore described, with thesocket A, of the extensions or legs a, formed on said socket, thespring-supported follower O, which fits the socket and can movelongitudinally therein, and the stops e, which are secured to thesocket, and the disk B, secured to the extenfollower and adapted toengage the lower edge of the socket.

2. The combination, substantially as herein- 5 before described, withthe socket A, the extensions or legs a, formed on said socket, thespring-supported follower G, which fits the socket and can movelongitudinally therein, the stops 6, which are secured to the follower10 and adapted to engage the lower edges of the sions or legs a, formedon the socket, and provided with a hole or holes, 0.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subl 5 scribing witnesses.
